Very eerie! I like the ambiance a lot.
Before the "melody" came in, I thought it would make for a nice intro to a prog-metal track, interestingly enough.
The stereotypical alien noise is the only thing that docked that half a star. It's a bit too cliché for the whole creepy-vibe ambient tune, in my opinion.
Otherwise, excellent job nailing the je ne sais quoi that causes a fear reaction solely based on sound. It may also have to do with my sleeptalking roommate, my extreme lack of sleep, and the dark environment, but I believe it's 99% due to the audio.
Glad you liked it! Originally it was going to be a 3-5 minute track with beat parts inbetween but the first minute sounded like a nice finisher for the ep. You might like my other track "vivid dark, full of colours", which is a bit more calm, but can creep you out at the same time. I'm really proud of it!
Again, thanks for the kind words!
